[Samba] Join AD DC Fail (LDAP_ENTRY_ALREADY_EXISTS)

[Chan Min Wai]

Hi Marc,

The 2 AD Dc was working until one day Power failure (or some kind)

And the AD Dc are having issue (I can see it on DC2)
When only DC2 is online there will be some issue


So I was trying to rejoin to the AD...

I think t take a wrong steps to try fixing it..
